STEAM CONNECTION.

Application led June 14, 1926, Serial No. 115,1743. Renewed November 20,1928.

This invention relates to a steam connection.

The general object of the invention is to provide an improved means forconnecting a source of power with a primer mover which is mounted torotate'.

One of the speciic objects of the invention is to provide a novel meansfor connecting high pressure and exhaust steam pipesv of a rotatablymounted engine with a relatively fixed boiler and condenser.v v Anotherobject of the invention is to pro vide a steam connection wherein thehigh pressure steam line through a portion of its length is surroundedby the exhaust steam lines. Y

Another object of the invention is to provide a connection forconnecting a fixed boiler and a fixed condenser with a rotatably 2Gmounted engine and wherein the high pressure line `and the exhaust lineare mounted to rotate coaxially.

Other objects of the invention will be apparent from the followingdescription taken in connection with the acompanying drawings wherein:

Fig. 1 is a central sectional view partly in elevation showing myimproved steam connection; Y

Fig. 2 is a fragmentary detail showing a portion of a vessel equippedwith my invention, and

Fig. 3 is a section on line 3-3, Fig. 1.

Referring to the drawing by reference characters, I have shown asupporting base 10 which may be a deck of a vessel. Mounted upon thisbase, I show a frame work 11 which supports a bull ring 12. Upon thisring 12, I arrange rollers 141 Vwhich support a platform 15. Theplatform isprevented from tilting by laterally arrangedv rollers 15.VMounted upon the platform 15, I show an engine 16. This engine 16serves to rotate a crane 17 about the frame work 11. The engine 16 alsoserves to operate the boom 17 and the cables 18 for lifting a loadsupported on the hook 19.

In order to supply steam to the engine 16 from a boiler, (not shown) theboiler is connected by means of a pipe 20 with a rotatable steamconnecting device indicated generally at 21. This rotatable steamconnecting device includes a central pipe or conduit 22 which isconnected to a pipe 23 plied to the engine 16.

so that high pressure Leerzeisteam be supnected to a hollow jacket 25which SurroundS the pipe'22. The jacket 25 terminates at 26 short of theend ofthe pipe 22 and the tion by means of a packing gland 30. Theymember 27 includes a chamber 30 which is below the end of the jacket 25.vThis chamber 30 comunicates througha pipe y31 with a condenser (notshown).

'lower end of the jacket isrotatably mounted The jacket is shown asprovided with a flange 35 which serves to hold/,the steam connectionvin'. place. vThe jacket 25 and pipe 22 are connected by members 31.

From the foregoing description it will be apparent'that as th'e'base15rotate'sthe` pipes 23 and 24 as well as the jacket 25,'

will Yrotate on this base. A guide member 36 is provided for preventingundue lateral `movement of the jacket 25. This guide member is xedandthe jacket moves within the guide member. The packinglmember 27 andgland 30 vare both fixed and the jacket 25 moves within the upperportion of the packing member 27 while the lower portion of the pipe 22moves Within the gland 30.

Having thus described my invention, I claim: l
